ZW series self-priming non-blocking sewage pump

ZW series self-priming non-clogging sewage pump is a product with novel structure successfully developed on the basis of repeated research on similar technologies at home and abroad. The pump integrates self-priming and non-blocking sewage discharge. It adopts the axial reflux external mixing type, and through the unique design of the pump body and the impeller flow channel, it can not need to install a bottom valve and irrigation and drainage as the general self-priming clean water pump. It can pump liquid containing large particles of solid and long fiber impurities. ZW series self-priming non-clogging sewage pump is mainly composed of pump body, impeller, back cover, mechanical seal, bearing seat, inlet valve, gas-liquid separation pipe, water adding valve, inlet and exhaust pipe.

Why choose our products:

The pump body is provided with a liquid storage cavity, and communicates with the pump working cavity through the upper return hole and the lower circulation hole to form an axial return external mixing system of the pump.

After the pump stops working, a certain volume of liquid has been stored in the pump cavity. When the pump is started, the liquid stored in the pump is thrown up by the air under the action of the impeller. The liquid returns to the working chamber through the grid of the gas-liquid separation tube, and the gas is discharged out of the pump, so that a certain The degree of vacuum achieves the effect of self-priming.

. Simple structure, good self-priming performance, strong sewage capacity, high efficiency and energy saving, easy to use and maintain .

The technical performance indicators of the sewage pump series products are leading domestically, reaching the international advanced level, and have broad application markets and development prospects.
